Study on impinging stream flow channel in abrasive flow polishing complex cavity of precision mold

摘要：

　　In order to solve the problem about polishing complex cavity of precision mold,to improve the efficiency of processing and reduce the surface roughness,putting forward multiple entries impinging stream processing device.With making use of the collision of two strands of abrasive flow,Realizing the mutual disturbance of abrasive flow in the runner,and increasing the collision between abrasive to improve the disordering of abrasive movement,for promoting abrasive polishing to mold cavity.Johnson-Cook elastic-plastic material model is set up at the same time,using abaqus finite element simulation to simulate the impact deformation wear and cutting wear with the increasment of impact times.
